Your Brain Under Pressure is a mental health education series from psychiatrist Dr. Tracey Marks that explains what happens in your brain and body when stress, anxiety, uncertainty, emotional pressure, and social threat take over. If you’ve ever felt unsafe for no clear reason, reacted before you could think, predicted the worst, replayed conversations, frozen under pressure, snapped and regretted it, struggled to calm yourself with logic, or felt mentally drained by small decisions, this series helps you understand why. Dr. Marks breaks down the neuroscience of the high-alert brain, threat perception, the stress response, emotional flooding, fight-flight-freeze-fawn responses, nervous system regulation, rumination, people-pleasing, workplace stress, burnout, recovery, attention, focus, decision fatigue, and mental bandwidth. You’ll learn why criticism can feel so intense, why one email can hijack your whole day, why meetings can drain your brain, why rest can feel uncomfortable when you’re burned out, why easy tasks can feel impossible under stress, and why your brain keeps following old patterns even when you’re trying to change. Each episode translates brain science into clear, practical language so you can recognize your stress patterns, reduce self-blame, and begin teaching your brain the difference between stress and danger. This series is for anyone who wants to better understand anxiety, overthinking, emotional reactivity, nervous system activation, burnout, workplace stress, relationship stress, attention under pressure, and the science of resilience. Learn how to strengthen your mind, fortify your brain, and build resilience under pressure.
